Procedure

A mixture of 5-(2,2-dibromovinyl)-2-propylpyridine (0.8 g, 0.0026 mol), potassium tertbutoxide (1.2 g, 0.0105 mol) and toluene (14 mL) were heated at 80° C. for 4 h. After completion of reaction, the reaction mixture was cooled to RT, diluted with water (15 mL), and extracted with EtOAc (3×50 mL). The organic layer was dried over anhydrous sodium sulfate and concentrated under reduce pressure to obtain product as a yellow oil (0.55 g).
